TYPE-WRITING MACHINE.

appncation ined Apu se.

To all whom it may concern f lie it known that I, IVILLIAM JONATHAN Nenne, a citizen of the United States, residing at Madison, in the count of Dane and State of Wisconsin, have invented a new and useful Improvement in Type-Writ ing Machines, of which the following is a specification.

My general invention supplies the opera-- tor of a typewriting machine with auto-- matic indicating means, called into Operation under the novel control of a typewriter part used in the operation of typewriting, whereby without exercising preliminary care he is able to inform himself of the position of his advancing sheet, so that he may know" at any time the extent of the matter completed on his sheet, and also the extent of the uncompleted portion of his sheet. It also lsupplies him with automatic indicating means, called into operation under the novel control of such a typewriter part, for indicating the arrival of the sheet into predetermined line positions through the use of various types of signaling and machine-lock devices.

The embodiments ofthe invention shown in the drawings employ an operative member that is actuated from a. pre-attained starting position through a connection with the sheet-advancing mea-ns, more specifically in this case the platen, under the control of a typewriter part as aforesaid. ThroughtheI said member the several indicating means are herein shown as called intov operation by the platen'. The construction of the mechanism as a whole is suchthat backing-up is automatically permitted from any position without affecting the indicating. The said embodiments within their range automatically re-set upon the usual forward removal of the sheet, whether the sheet is completely printed or not, and thereafter when the'new sheet is inserted and printed they automatically enter upon their indicating duties and indicate tothe operator by means of indices the respective numbers of the lines, counting from the usual first line printed on the sheet, or as desired, all without preliminary care on his part. They also give him a warning signal by means of belltrip devices, and lock the Specification of Letters Patent.

printing, either or both.v when he has written predetermined numbers of lines, and thereafter release said printing instrumentalities for use on the succeeding sheet, all without preliminaryv care on his part. They also enable him to Write a folio number or similar marking at the head of his sheet without counting' it as a first line, without care on his part as respects the counting. They also indicate for him Without preliminary care as respects that sheet, by means of indices, the decreasing distance from his current printing point toI a predetermined point on the sheet such as the sheet-end, or the predetermined page-end. I believe that none of these functions has heretofore been thus performed in typewriting machines without preliminary care, in the case of each sheet printed, on the part of the operator.

Other novel features and uses are as hereinafter described.

Some of the features of the invention and novel combinations of elements as shown in the drawings and described and claimed herein are intended for sheet-position-indieating uses not necessarily limited as respects the inclusion of control by a type- Writer-mechanism part as aforesaid.

Fig.4 VI is an end elevation of a modification showing the line-space lever as so used. Fig. VII is a detail view of portions of Fig. VI. v

In the drawings the usual main frame of a typewriting machine is indicated at 4l, the transversely movable carriage-frame at 12, the' paper-table at 8, the platen-roll -for advancing the sheet at 10 mounted fixedly upon its arbor 13 which is journaled near the ends in the carriage-fra1ne, the paper-sheet in the machine at 45, the line-space lever` for advancing the platen and through it the sheet at 51, the type-key levers at 58 connected with usual type-carry ing parts not shown herein, the type-keys at 59. thespace-key levers at 38, and the space-keys at 39. The said usual typewritermechanism parts are old; they are or may be of' any approved type, as in practice.

The embodiments of the invention illustrated in the several figures employ an operative member that is rotary and which for convenience is mounted to revolve about a different axis from that of the platen. As specifically shown herein the said member has a toothed connection with the platen, but is disconnectible therefrom, and tends to return into initial position when released from thc control of the platen through the action of an eccentrically mounted weight thereon. The invention in its broader aspects however is not limited to the employment of a particular type of driving means, nor to the employment of a. particular type 'of moans for giving the member its initial position.

Referring to the embodiment. shown in Figs. l to lV,-P`laten arbor 125 has fixedly attached thereon, as by means of a key, a toothed driver `wheel 11. Mounted on carriagerame 12 as by means of screws 14 is frame-extension 22, bearing pin 9, upon which is journaled hood-piece 31. Said hood'piece serves to support the ends of arbor 21 journaled in the'side walls thereof. Arbor 21 bears mounted thereon side by side the toothed wheel 5, index-carrier 6 and indexharrier 6h, the said mounted parts being angularly adjustable as will he explained but operating as a unit. Wheel 5 is adapted to mesh with wheel 11 in one position of the hoodpiece. but the center of gravity of the hood-piece and its supported parts is Well to the right of its axis at 9, and wheel 5 tends to be held out of mesh 'with Wheel 11 by the weight of the said parts. Said Wheels may therefore be described as normally out lof mesh. Index-carrier 6a previously rei ierred to is supplied with the cccentrically disposed Weight 25, which acts rotatively upon said carrier, except When Wheels 5 and l1 are in mesh, to bring the carrier always into a constant position with the same portion of its periphery adjacent to pointer 18 on the hood. This position may be termed its initial or starting posit-ion. Wheel 5 aforesaid bears a projection 2O 'pivoted upon pin 23 and held in working position by Stoppin 24. That is to say, the pro]ection adapted to act operatively upon cooperating parts in the path thereof when operated forwardly against them, but to give Way when operated -backwardly against them. The purpose of the provision is to supply -a safeguard in addition to the general con struction to insure unobstructed backward operation of the mechanism however used.

Hoodpiece 31 carries pin 40 bearing; hell 27, and it also carries pin 29 upon which is journaled trip-lever 28 having bell-harn- Iner 26 attached thereon. One end of said trip-lever is turned in at right angles toiva rd the carriage-frame', a slot 30 in the hoodpiece permitting 'the turned end of the said trip-lever to project past the hood-piece into the path of projection 20 aforesaid. Frame extension 22 bears also a pin 7, on which is journaled elbow-lever 1 whose upper arm 19 extends into the path of projection 20 aforesaid. The lower arm of said elbow-lever bears a roller or cam-follower 4, adapted to cooperate with a cam-face 15 on the lower part of hood-piece 31 aforesaid. Said cam elements act When in the position shown in Fig. 1 to maintain the hoodpiece in its position farthest toward the platen arbor With toothed Wheel 5 in mesh with its driver 11, but when roller or cam-follower 4 is raised past the swell of the cam, hood-piece 31 is permitted thereby to rock 'away from the platen arbor and toothed wheel 5 passes out of mesh with its driver 11. The lower arm of elbow-lever 1 also supports one end of bail-bar 3, which extends parallel with the platen axis from one end of the platen to the other and is supported at the latter end by parts corresponding tosaid lower arm of lever 1, pin 7, and extension 22. Wearing loosely upon this bail-har is rod 2, the arrangement being such that the bail-bar is movable transversely with respect to the rod Without ali'ecting the position of the rod but when it is moved about its axis at 7 the position of the rod is affected. That is to say, the parts constitute a universal connection between operating elements on the carriage and indicating elements on the main frame, as" will be hereinafter described, by means of which the said indicating elements are operated from said operating elements in every position of the carriage, irrespective of the lateral movement of the carriage. The lower end of rod 2 is adjustably attached into the Wooden cross-,bar 36 by means of nuts 33, at a point about central of the cross-bar. Attached at the ends of cross-bar 36 as by means of screws 34 are the slotted rack-pieces 35, each of which is supplied with a toothed rack 46 adapted to mesh with a toothed segment 47 on arbor 48 iournaled at the ends in main .frame 41. The central portieri of said arbor 48 constitutes lock-bar 50, so shaped that when it sustains a position more or less Vertical the type-key levers 58 cannot be depressed, but are locked, outwvhen it sustains a position at ino a greater or less angle to the vertical said levers can be depressed as usual. or are released; but the lock-bar is preferably made sutliciently short not to engage space-key levers 38 so as not to lock themv ln order that the locking action may be more positive and be effected by a greater range of movement of the lock-bar, I construct said bar with its locking edge turned over to form an are, and I construct the type-key levers with arecess as at Gl into which said lock-bar may pass when in the position occupied before locking. Each of the usual two space-key levers 38 bears a pin 87 which works in the slot 49 in the corresponding slotted rack-piece 35 before mentioned.

In Fig. I the mechanism is shown in about the position it would assume shortly before the predetermined time to remove the sheet. An additional rotative movement forward of the platen from the position shown will through toothed wheels 11 and 5 cause projection 2() to actl against the turned-in portion 32 of trip-leverQS, hammer 26 will be raised land then released, and the bell 27 will be struck a blow against its edge from within. The operator will thereby be informed that his next line (say) is his predetermined last line. Upon the completion of that line an additional advance of the platen will cause projection 20 to act upon end 19 of elbow-lever 1 and move it a short distance toward the platen-arbor. thereby raising bail-bar 3, rod 2, and cross-bar 36, and through racks 46 and toothed segments 47 rocking lock-bar 50 into locking position under key-levers 58. The printing instrumentalities are now rendered inoperative for use. turned forwardly by the operator in usual manner to remove the sheet. This foro ard rotation of the platen will cause project-ion Q0 to move lever-end 19 further toward the platen-arbor. cam-follower 4 will thereby be raised further along the cam-face 15 of hood-piece 31 and past. the swell of the cam, and the hood-piece will rock by gravity about its axis away from the platen-arbor following the support of the cam-follower aforesaid, bearing toothed wheel 5 out of mesh with toothed driver 11. The moment these toothed wheels become disengaged, weight 25 is rendered etfective to rotate carrier G and connected parts so as to bring the carrier to rest always with the same point on its periphery opposite pointer i3. as will always occur when said weight finds its center of gravity. This peripheral point may be supplied with the index 1. The said forward turning movement of the platen that results in the re-setting ot' the indexcarrier as desecribed into initial position, results also in the releasing of the locked Ordinarily the platen will now be pieces 35 under the actuation of projection 20 acting through racks 46 aud segments 47 to rock lock-bar 50 into a non-locking position past the vertical.

It will be seen that both the resetting and lock-releasing actions described as resulting from the usual forward turning ot' the platen will occur when the sheet is thus removed. irrespective of the stage oi' the printing, so that the automatic action of the mechanism will not be affected by the removal of a sheet containing a shorter than the predetermined page. In the said position the parts ordinarily remain until a new sheet is inserted and advanced into printing position. The operator may first, as is often desirable. begin his sheet by numbering it. lf so. his operation ofthe type-keys 59 will leave the indicating meehanism undisturbed, and it will not be aff fected by the succeeding advance of the sheetl into the desired position tor printing the first body line. During the printing of the first Vword of said lirst body line the parts will still remain undisturbed; but between the first word and the second the op erator will use the space-key 39 in ordinary manner, space-key levers 38 are depressed, pins 37 thereon act upon slotted rack-pieces 35 to lower them. and through cross-piece 36, rod 2, bail-bar 3 and elbow-lever l swing cam-roller 4 downward along cam-face 15 of the hood-piece. causing the hood-piece lto rock toward the platen arbor and bringing toothed wheel 5 into mesh with toothed wheel 1l. Upon con'tpieting his first line, the operator will rotate the platen suliciently to advance the sheet into position for receiving the second line. ndex-carrier G, now connected to rotate in unison with the platen, will by this action be rotated so that a new portion thereof is brought into indicating position. This portion may be supplied with anl index 2 to indicate that the sheet is in position to receive the second line, and the third-line position oi the sheet can be indicated by means of an index 3 on the carrier likewise. and so on to the end of the sheet. or as for as may be desired. That is to say, the indicating mechanism more particularly illustrated in Figs. 1 to IV is controlled by or from the key-levers, or more specifically the space-key levers; or more broadly considered. the indicating mechanism is controlled by or from a typewriter-mechanism part used in the typewriting operation, the invention being not considered by me to be limited as regards the precise typewriter-mechanism part employed for the purpose.

For the purpose of supplying an adjustment provision by means of which the bellstriking and machine-lock devices can be printing tneclumism. the additional move-- l caused to act. at any predetermined time or ment of lever l7 hail-bar f3, rod 2 and racki line-position. 'projection Q0 and weight 25 are caused to be relatively adjustable angularly as follows: projection provided with a frictional split spring hub 17 over which carrier (8L bearing said weight may be pressed and by means of which said carrier is held more or less tightly against said whl. A guide-point 44 projecting from the rim of said wheel so as to cooperate with the indices on the carrier assists the operator in making the desired adjustment. 1f, for example, the ma.- chine is intendedto be locked after the printing of thirty-five lines, carrier GtL is pressed over split spring hub 17 in such angular position that index 35 thereon is in position opposite said guide-point, as in F ig. III. The bell will now sound (say) upon the advance of the sheet into position for receiving the thirty-fifth line, and the 1na- -chine will be locked after its completion, upon the succeeding advance of the sheet.

I show in my drawings, F II, III and 1V, a second index-carrier 6b, marked to count progressively downward instead of upward the lines upon the sheet being printed. In the case of a )age of a predetermined length of (say) t irty-eight lines, said carrier would be adjusted relatively to carrier G until index 38 on carrier 6b was in position opposite index 1 on carrier 6, as in Fig. I1, spring hub 17 thereafter acting to hold the parts united so that they will rotate in unison. During the time that carrier 6a is counting ascendingly from (say) the first line position on the sheet, carrier 6b will now be counting descendingly, enabling the operator to tell at a glance just how much printing space remains for use in the predetermined page-length. Carrier o" can be adjusted to indicate the distance to other points on the sheet, if desired, such as the bottom edge thereof.

Split spring hub 17 that is used to bind wheel 5 and carriers 68 and 6* together, but in adjustable relationship, consists of two or more spring tongues attached upon said toothed Wheel adjacent to the axle thereof. Said tongues are each given a reverse curve as shown, so that friction-surfaces 16 of the respective carriers may bear upon the tongues in the one case exteriorly and in the other interiorly. Such 'construction permits the carriers to be readily adjusted or replaced. The carriers shown are inexpensive and easily removed; lf pro'ose to use in practice a set of interehangealile carriers bearing indices suitable for use with the different line-spacings, or when desired counting by units other than the line-unit.

It to be noted that the employment ot f an adjusting` means is not essential in the Wheel 5 bearing said carrying out of the invel'itiou. nor it such adjusting means are employed is the characier ot'rthe same essential. lt is to be noted also that m practice l propose to employ at times any one of the several types of indicating means described, and not the others, or any two or three instead ot' all.

In the embodiment illustrated in Fig. V the action of the mechanism is the same :is has been described, except that the use of a type-key lever through the action thereof upon the underlying crossbar 52, instead of the space-key lever, calls the previously reset operative member into action.

ln the embodiment illustrated in Figs. Vl and VII, the action of the mechanism is likewise substantially the same, except that the use of the line-s ace lever 51, as in advant-ing the sheet a ter the printing of the first line, is availed of to call the previously re-set operative member into action, instead ot that of the space-key lever, and the locking arrangement is slightly modified in ioiai. An arm 53 of said line-space lever engages upon lever 54 and rocks said lever, which is journaled upon pin 56 on the carriage-frame, thereby through link 55 and pin 57 on hood-piece 31 rocking said hoodpiece toward the platen-arbor and rendering the driving means effective to operate the operative member. Cam-roller 4 follows caln l5 by its own gravity and that of the attached parts` thereby holding the toothed wheels in engagement.

.lo simplify the drawings, in the case of Figs. V and Vl the bell-devices are omitted. lt is to be understood, however, that usually in practice bell-devices will be employed.

The term typewriting operation as used herein is intended to signify not only the printing but other portions of the general operation ot' typewriting, including the use of thevarious parts and attachments at the oomman d of the operator for facilitating his worin-that is to say, including the use of the various typewriter parts of a typewriting machine.
